VACUUM-CLEANER.

Specification of ietters Patent.

Patented June 1, 1915.

Application filed July 2, 1914. Serial lio. 848,573.

To (1Z5 whom it m ay concern Be it known that 1., JOHN B. De Cosra, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful li'nprovements in Vacuum-Cleaners, of which the following is a specification.

My invention relates to inu'iroveinents in vacuum cleaners, and the ii'n'ention consists in certain novel features of construction, combination and arrangement of parts hereinafter described, and particularly pointed o t in the claim.

in order that the invention may be fully understood, reference will now be made to the accompanying drawings, in which:

Figure 1 is a side elevation of a. vacuum cleaner eu'ibodying my invention. 2 is a horizontal longitudinal section on line Iii-ll oi": Fig. l. 1' 1g. 3 is a broken detail section on line Iii-ill: otf Fig. 4% is vertical longitudinal section on. line Il 1V oi? lfiigg'. 5 is im'crted plan View of the cl aner. Fig. (3 is an eleration oi a bail forming pa rt the invention. 7

ln carrying out the invention, I employ a case 1, having a removable suction nozzle 2, extending across its lower trout portion. Said suction nozzle 53 communicates with a dustbap; 3 arranged in a chamber 4%. The rear end of the dust-bag: 3 is folded and held in closed position by a clamp G designates a bellows communicating with the cliiamher t, to creating a suction through the nozzle 2. The foregoing of ordinary construction, hence further description there of is deemed unnecessary.

designates a pair otrubher tired traction wheels inoimted upon an axle '4, journaled in a pair of bearings 8. Said traction wheels 7 actuate the bellows Gihrough the intermediacy pair of connecting-mt 21.

10 designates a rotary broom, or sweeper, fixedlyaneuni" upena twisted wire shaft 11, carrying: at ends a pair of friction Wheels 12, which engage the peripheries ot' the trzmtion win Is 7, which dr e trietion wheels 12-. The l riction wheels liha e jive a pair of trunuions 1-iupon which said UflC'iJlOil wheels are journaled.

Trunnions 14': are mounted upon fiat springs 15., secured to the sides of the case 1 by screws 16. By mounting the trunnions (T a I the hubs of the friction wheels 12 and the adjacent sides of the case, as disclosed by Figs. 2 and 5.

l8 designates a dust pan pivotally-mounted in the rear of the sweeper 10, to receive the sweepinrzs gathered from a floor by said sweeper. Said dust pan 18 is pivotallymounted upon a rod 19, secured to opposite sides of the case 1. By thus pivotallyn'iounting the dust pan 18 it may be swung to open position, as indicated .by dotted lines, Fi 4, for the'purpose of emptying its contents therefrom. The dust pan 18 is normally held in closed position by a pair of coil springs 20, secured at their lower ends to said dust pan and at their upper ends to pins 21 extending inwardly from the adjacent sides of the case 1.

22 designates a deflector extending partway over the front side of the sweeper 10, to deflect the sweepings carried up thereby into the dust pan 18. i

23 designates a bail pivotally-secured by pins or screws 24, to opposite sides of the case 1 to receive ahandle 25, whereby the sweeper is pushed to and fire over a floor. Said bail has a reinforcing. strip 26 at its upper transverse portion, through which a screw 2'? extends to secure the handle 25 to said strip -The handle 25 may be unscrewed froin the screw 27 when the sweeper is to be shipped or stored.

28 designates a. pair of resilient bail retainers secured at opposite sides of the case 1, to hold the bail in the forward-position disclosed by dotted lines, Fig. 1, so that the sweeper may be carried with its rear end .ownward to preyent spilling the contents 1 the dust pan 18.

29 designates a trip pivoted at the upper rear corner of the case 1, for the head of the purpose of tipping the forward end of the sweeper to'raise the suction nozzle above obstructions on the floor. The trip 29 may be swung out of the path of the screw 27, to j allow unrestricted pivotal movement of the handle 25, when desired. I From the foregoing description, it is apparent that I have produced a sweeper of comparatively simple and inexpensive construction, and embracing a number of new and novel features which cooperate in addins, to the elficiency and convenience of hendling said sweeper. Haivingthus described my invention, what I claim and desire to secure by Letters Patent, is:

In a machine of the character described, a

case, aibail pivotally mounted upon saidcase, a transverse reinforcing member on said ball, a headed screw extendlng through the bail and said reinforcing member, a

handle removably engaged by said screw,

anda trip pivoted to the case and adapted tov be engaged by the head of said screw.

In testimony whereof I afiix my signature,

in the presence of two witnesses.
